Striping Whitespace

[07KingKaiju07]

Hello guys,

I'm trying do a simple bit of code that removes trailing whitespace from text and then prints but i can't get it to work.
I'm really struggling with basics understanding of how to use the modules correctly if anyone can explain that would help a lot. I'm reading the base library but I am not understanding how to use it properly. The equivalent of what i am trying to do in python would be:

fav_language = "Motoko "
print(fav_language)**
output:'Motoko '

fav_language = fav_language.rstip()
print(fav_language)**
output:'Motoko'

import Debug "mo:base/Debug";
import Text "mo:base/Text";

actor {

// Stripping Whitespace.
var favourite_language = "Motoko ";
Debug.print(debug_show(favourite_language));

favourite_language = favourite_language.stripEnd();
Debug.print(debug_show(favourite_language))

};

The syntax should not be
favourite_language.stripEnd()
It should be
Text.stripEnd(favourite_language, #text " ")
stripEnd is a function in Text library so the syntax is Text.stripEnd()
Inside the stripEnd() we got 2 variables:
func stripEnd(t : [Text], p : [Pattern]) : ?[Text]
There are t is your Text, and p is the pattern Pattern = {#char : Char; #text : [Text]; #predicate : (Char -> Bool)}
In this case, we want to delete the white space in the text so we use #text " "

Here is the code:

actor {
    // Stripping Whitespace.
    let favourite_language = "Motoko ";
    Debug.print(debug_show(favourite_language));
    let favourite_language1 = Text.stripEnd(favourite_language, #text " ");
    Debug.print(debug_show(favourite_language1));
};

Thank you that clears up a lot for me!
This answer is showing me how to interpret the information in the Motoko base library correctly and how to structure my code ty!
